In This dissertation, an effective rotor shape optimization for torque ripple reduction of the Double Stator Switched Reluctance Motor (DSSRM) is presented. This method leads to a lower torque pulsation as well as significant increase in the average torque. The method is based on the shape optimization of the rotor using Finite Element Method (FEM). Rotor reshaping is based on redistribution of the flux so that the phase inductance profile has a smoother variation as the rotor poles move into alignment with the excited stator poles. Steady state analysis is conducted to evaluate effects of the new rotor shape. Finally, to check on the robustness of the new design, 3-D FE mechanical analysis is used to evaluate structural resistance against local electromagnetic forces. The results show that this shape optimization technique introduces a profound impact on the torque ripple reduction and at the same time increases the average torque.
